Question: how is the compilation order reported?

Hello! I have a question regarding how the compilation order is reported. The tool UI shows:

However, nmethod compile_id=''is forjava.lang.Object <init> ()V`

Full XML tag

<writer thread='163103'/>
<nmethod compile_id='1' compiler='c1' level='3' entry='0x000071ba5d4001a0' size='760' address='0x000071ba5d400010' relocation_offset='352' insts_offset='400' stub_offset='624' scopes_data_offset='688' scopes_pcs_offset='704' dependencies_offset='752' metadata_offset='672' method='java.lang.Object &lt;init&gt; ()V' bytes='1' count='262' iicount='262' stamp='0,054'/>

But based on the screenshot above, java.lang.String isLatin1 is the first class compiled and this has an ID 4.

I assumed the compilation order is for a specific thread but that also does not seem to be the case because the first class compiled in thread 163103 is java.lang.String hashCode.

How exactly is the log being parsed to show the compilation order?
